摘要： An automatic smoke/carbon monoxide detection system and method are described that are configured to automatically shut off power supplied to an appliance/equipment, a room of a structure, a zone within a structure, or an entire structure upon detection of smoke/carbon monoxide/hazardous gases. A system and method are further described herein that are configured to connect to an on-board diagnostic port, where upon detection of smoke/carbon monoxide/hazardous gases exceeding a certain level, an alert is displayed/sounded so that the driver/passenger of the vehicle can act appropriately. Alternatively, a command may be issued to shut off the engine of the vehicle to immediately halt the production of deadly gases.

摘要： A cabinet security assembly includes a housing that is mountable to a cabinet door such that the housing is positioned within a cabinet when the cabinet door is closed. A light emitter is coupled to the housing and the light emitter emits light outwardly from the housing when the light emitter is turned on. A receiver is coupled to and extends away from the housing. The receiver is comprised of a translucent material to pass light therethrough. The receiver insertably receives a handle of the cabinet door to transfer the light from the light receiver into the handle for ornamental purposes. A lock is movably coupled to the housing and the lock is actuatable into a locking position to engage the cabinet for locking the cabinet door in a closed position.

摘要： A smart light-emitting-diode (LED) bulb includes apparatus enabling the bulb to be turned ON, OFF, or dimmed without the use of a wall switch. Such apparatus may include circuitry responsive to rotating the LED portion of the bulb, circuitry responsive to touching or tapping on the bulb, or a Bluetooth or WiFi interconnection enabling the bulb to be controlled using a smartphone or other device executing a bulb-control application. Other apparatus may include a microphone enabling the bulb to be controlled with a voice, sound or music. In other embodiments, apparatus enabling the bulb to be turned ON, OFF, or dimmed may include a power line communication (PLC) interface enabling the bulb or bulbs to be controlled via the Internet. A camera or image sensor may be provided enabling the bulb to be gesture-controlled. A system may include a plurality of smart LED light bulbs.

摘要： Arrangements for controlling a climate control system are provided. A hazard detector of a group of smart devices may detect a carbon monoxide (CO) alarm condition at the hazard detector. The hazard detector may transmit, via a relatively low-power mesh communication network, an indication of the CO alarm condition to one or more other smart devices. A spokesman node of the relatively low-power wireless communication network may translate the indication of the CO alarm condition from a first wireless communication protocol to a second wireless communication protocol. The spokesman node may transmit the indication of the CO alarm condition to a system controller via a relatively high-power wireless communication network and the second wireless communication protocol. A system controller of the climate control system may transmit a signal to turn off at least part of the climate control system.

摘要： Various arrangements for assessing an installation of a smart home device are presented. An orientation of the smart home device may be analyzed to determine whether the orientation of the smart home device is unsuitable for one or more features of the smart home device to function properly. An indication of whether the orientation of the smart home device is unsuitable may be output, such as by the smart home device using voice or lighting.

摘要： An internal combustion engine-based system including an engine, a shutdown circuit coupled to the engine to shut down the engine, a controller in communication with the shutdown circuit, and a carbon monoxide (CO) sensor in communication with the controller. The controller communicates with the shutdown circuit to shut down the engine at a predetermined CO threshold concentration when the CO sensor provides the controller with signals that are representative of a CO level proximate the engine that indicate a trend of building CO levels over a set time interval.
